Variation between and within populations in a provenance trial of Pinus sylvestris at Nordanås, lat. 64 19', long. 18 09', alt. 400 m

Data on survival, stem height, stem volume and yield per hectare from a provenance trial with Scots pine (Pinus sylvestris) at Nordanås, lat 64o19', long 18o09', alt 400 m, are presented in this report. Regression analyses were carried out to test the influence of transfer on the parameters studied. For the most important characteristics, yield per hectare and survival, it was found that a transfer by 1-2 latitudes southward will imply an improvement. Since the progenies from individual trees within the populations were kept apart the variation within populations could be analysed. This variation was found to be considerable both for survival and height in some of the populations.
